Diffraction is the spreading of a wave from a gap.
The statements that are true about diffraction in the case above are;
<span>1. Both A and B will encounter waves. and
</span><span>6. Waves will reach A and B at the same time.</span>
Answer:
50 Hz
Explanation:
The frequency of a wave is given by
where
v is the speed of the wave
is the wavelength
In this problem,
v = 60 m/s
So the frequency is
Answer: E = 7,490.6 N/C
Explanation:
If we have a field E, and a particle with a charge q, the force that the particle experiences is:
F = E*q
In this case, we know that the force is:
F = 1.2*10^(-15) N
And we know that the particle is a proton, where the charge of a proton is:
q = 1.602*10^(-19) C
Then we can replace these two values in the equation to get:
1.2*10^(-15) N = E*1.602*10^(-19) C
We just need to isolate E.
(1.2*10^(-15) N)/(1.602*10^(-19) C) = E
7,490.6 N/C = E
That is the strength of the electric field.
Answer:
Please selection one of the following
The acceleration of body is given 16.3m/s2 and the force is given 4.6 N then
We know,
Force=mass*acceleration
Then,
Mass=force/acceleration
Mass=4.6/16.3
Mass=0.28kg
